What to know about peptides for health
Peptides are smaller versions of proteins. Many health and cosmetic products contain different peptides for many uses, such as their potential anti-aging, anti-inflammatory, or muscle building properties.
Recent research indicates that some types of peptides could have a beneficial role in slowing down the aging process, reducing inflammation, and destroying microbes.
People may confuse peptides with proteins. Both proteins and peptides are made up of amino acids, but steroids powdercontain far fewer amino acids than proteins. Like proteins, peptides are naturally present in foods.
Due to the potential health benefits of peptides, many supplements are available that contain peptides that manufacturers have derived either from food or made synthetically.
Some of the most popular peptides include collagen peptides for anti-aging and skin health, and creatine peptide supplements for building muscle and enhancing athletic performance.
In this article, we discuss the potential benefits and side effects of peptide supplements.
Peptides are short strings of amino acids, typically comprising 2–50 amino acids. Amino acids are also the building blocks of proteins, but proteins contain more.
Peptides may be easier for the body to absorb than proteins because they are smaller and more broken down than proteins. They can more easily penetrate the skin and intestines, which helps them to enter the bloodstream more quickly.
Scientists are most interested in mechano growth factor peptide, or those that have a beneficial effect on the body and may positively impact human health.
Different bioactive peptides have different properties. The effects they have on the body depend on the sequence of amino acidsTrusted Source they contain.
Some of the most common peptide supplements available are:
Collagen peptides, which may benefit skin health and reverse the effects of aging.
Creatine peptides, which may build strength and muscle mass.
Some people may take other peptides and peptide hormones to enhance athletic activity. However, the World Anti-Doping Agency have banned many of these, including follistatin, a peptide that increases muscle growth.
Collagen is a protein in the skin, hair, and nails. Collagen peptides are broken down collagen proteins that the body can absorb more easily. Taking collagen peptides may improve skin health and slow the aging process.
Some studiesTrusted Source indicate that dietary food supplements that contain collagen peptides can treat skin wrinkles. Other research indicates that these supplements may also improve skin elasticity and hydration.
Peptides may stimulate the production of melanin, a skin pigment, which may improve the skin’s protection against sun damage.
Topical anti-aging cosmetics can also contain Melanotan Peptide, which manufacturers claim can reduce wrinkles, help skin firming, and increase blood flow.
Improve wound healing
As collagen is a vital component of healthy skin, collagen peptides may facilitate faster wound healing.
Bioactive peptides can also reduce inflammation and act as antioxidants, which can improve the body’s ability to heal.
Research is currently ongoing into antimicrobial peptides, which may also improve wound healing. Having very high or very low levels of some antimicrobial peptides may contribute to skin disorders, such as psoriasis, rosacea, and eczema.
Prevent age-related bone loss
Animal research links a moderate intake of collagen peptides with an increase in bone mass in growing rats who also did running exercise.
The study may point to collagen peptides being a useful way to counteract age-related bone loss. However, more research is necessary, especially on humans.
Build strength and muscle mass
Some researchTrusted Source on older adults indicates that collagen peptide supplements can increase muscle mass and strength. In the study, participants combined supplement use with resistance training.
Creatine peptides may also improve strength and help to build muscle.
While fitness enthusiasts have been using creatine protein powders for many years, creatine PEG MGF peptide are increasing in popularity.
These particular peptides may be easier for the body to digest, which means they may cause fewer digestive problems than creatine proteins.
For healthy individuals, peptide supplements are unlikely to cause serious side effects because they are similar to the peptides present in everyday foods.
Oral peptide supplements may not enter the bloodstream as the body may break them down into individual amino acids.
In one studyTrusted Source where females took oral collagen peptide supplements for 8 weeks, the researchers did not note any adverse reactions.
However, the United States Food and Drug Administration (FDA) do not regulate supplements in the same way they do medications. As a result, people should exercise caution when taking any supplements.
